I played around with the program a bit. The SUB 'FadePal' seems to work now.
Looks a little different than playing the original in DOS.
I haven't found a solution for the ADLIB sound.
So I changed the original to play all the sounds in a row with a 2 second pause.
Run the program in the DOSBOX and record the sound in Windows at the same time.
Then everything is broken down into small sounds (OGG) and added back to the top of the game.
In the ZIP file I have added the sounds and the include files.

'Info & Requirements
'-------------------
'Graphics for this program were made using SPRITE 2.0.
'Adlib sound effects were made using FX.
'Requires a VGA.
'Recommend 386 or higher processor, and a sound card.

'Running QBInvaders * Important read this ! *
'-------------------
'Playing under DOS:
' Type qbasic /run qbinvade.
'
'Playing under WIN 3.1 and WIN 95 :
' Use the File Manager and double click on the MSDOS shortcut.
' Why?
' Some key combinations are reserved to windows like ALT-SPACE
' combo used by this program. Using the MSDOS shortcut realeases
' this key combo for Qbasic, preventing program errors.
'
'-------------------
' Program options
'-------------------
' (1) Change the 'UseFX' variable to false for PC speaker sounds.
' (2) Change the 'Hard' variable to true for harder gameplay.
' (3) Two graphics set are available.
